not very big I'm afraid.. but this concrete bmx/skate park was happily the second site I passed today where extensive engineering projects were being undertaken in the interest of improving cycling facilities..

the other was a site where construction was underway on a very large purpose built and very permanent bridge to carry cyclists on Sustrans route 2 over the tidal Culm without having to navigate near to any 'orrible dirty and dangerous motor vehicles..

My pic doesn't comply wi #3 as it's back in 2006 but it's definitely classed as "Earth Moving Plant" so what the hell, i'll include it - taken at our local quarry where i used to have a 50ft chute down a very sheer slope with a smooth transition into and out of before they blew up the side of the hill for hardcore. The chute was pretty sheer as my wheels barely touched the surface till i started to contact the transition, i doubt i'd have to balls to ride anything similar these days.

Ok, this was an easy one for me as there's a new road going in not especially far away.

Annoyingly that was as close as I got to a parked truck - the plan was to wait until the big trucks had stopped for the night, then get a cheeky ride along the new road cutting trail once they'd all gone home - then go up and have a proper look at the (parked up) trucks / excavators (like the small boys we are).

We hung about for a bit, but it didn't ever go quiet - once the big trucks stopped, service trucks / pickups then appeared all over the place, so we gave up. Whilst just chatting (as you do) I was told that one of the diggers on site was capable of filling a mover in five bucket loads.
